Preparation method of aluminum silicon carbide electronic packaging box body connector hole

The invention relates to the field of electronic packaging, and discloses a preparation method of an aluminum silicon carbide electronic packaging box body connector hole. The method comprises the following steps: manufacturing a silicon carbide prefabricated part according to a set size and structure, and processing mechanical characteristics such as an electric connector hole, a screw hole and the like on a porous silicon carbide prefabricated part; secondly, pre-filling the holes with aluminum alloy powder or blocks, and forming a silicon carbide prefabricated part pre-embedded with aluminum alloy; then preparing an aluminum silicon carbide green body by adopting a vacuum air pressure infiltration mode; and finally, machining the blank body, and machining the blank body to the aluminumsilicon carbide box body with the electric connector hole. The method can solve the problem that the aluminum silicon carbide box body is difficult to machine the electric connector hole, and is suitable for batch production.
